SKYLIGHT AND SIMILAR STRUCTURE.

Specification olLLetters Patent.

Application 'led August 9, 1909. Serial No. 511,865?

T o all 'whom/ 'gf may concern:

l Be it knofn that I, OTTO KrrzELMAma citizen of th'el United States, residing at Chicago, in the county of'Cook and State of Illinois, have invented certain new and useful Improvements in-Sl'{ylights and VSimilar Structures, of which the following is a specification.

a strong, simple skylight or similarstru'cture, the framework of which consists-of concrete.

In the accompanying drawings, Figure 1 is a fragmental top plan view of a skylight embodying the features of my invention. Fig. 2 is a transverse section on line 2 2 of Fig. 1. Fig. 3 is a section on line 3 3 of Fig. 2.

In the embodiment selected for illustration, the vertical side Walls or curbs Il are of concrete, the upper edges of Asaid curbs being inclined to correspond with -the slope of the roof, and having recesses 2 therein at suitable distances apart to receive the rafters enterilg into the construction of said roof. The ri e beam.3.is herein shown. as of c oncrete. xtend'mg from the ridge beam 3 to thercurbs 1 are 'rafters 4 of reinforced concrete. In this instance, therafter l is reinforced by two bars embedded therein and unconnected with each other. The ends of the bars liela suitable distance below the upper surface `of the' ,fi-after and near such upper surface, while the major portion of the bar 5 is-bent downwardly to extend to In the form shown, the raftersf14 are supported by the ridge beam-3 through the medium of metal posts or bars ti embedded in the ridge beam, andY projecting from the sides thereof. The rafters 4 have openings 7 formed therein to receive the bars 6. The outer or lower endsV of the rafters 4 lie within the recesses 2, the,uppersurface of the 4rafters being preferably substantiallyv flu ht' vith the upper edge of the curb. The rafters 4 may have shoulders 8 thereon, as heringshown, to lie in Contact with the inner surface of the curb 1 and thereby resist the ltendency of said rafters to longitudinal downward displacement.

9 are'sheets or lplates of glass or other suitable material extending from the ridge beam 3.to the curb 1 and from one of the rafters 4 to an adjacent rafter. Interposed between "le rafters 4 and piates 9 are strips s. he objectof thisinventioniis to produce- 9aof felt or other suitable material, which strips underlie theadjacent edges of the ad]acent plates. y, The plates 9 are secured in place by meansof'caps 10 voverlying the adjacent edges- Yf-ith'eadjacent 'plates and extending from` the ridge beam `3 to theouter ends of the plates.- The cap 10 is vheld in close Contact with the plates 95o as to clamp said plates-in 'place byI means .ofi bolts-11 Patented July 8, 1913.'-

which are fixed 1n the rafter tand by means of a bolt 12 which extends through an opening 13 in the rafter and is anchored in the curb 1, the bolts 11 and 12v extending through said cap. If desired, a hook 14 may be formed upon the outer ends of each cap 10 to receive the outeredges of the plates 9, and thereby assist -in securing said plates in place. On the upper ends of the bolts 11- and 12 are nuts .15. The upper edges of the plates 9 are covered by a cap 16 extending longitudinaliywof the ridge beam and overlying the upper edges of the plates and thel upperendslof the caps 10. The cap 16 is vsecured in .place by means of bolts 17 fixed in the ridgefbeam and extending through said cap, nuts-,18 being turned upon the upper4 ends 'ofw'saidrbolts Drain openings 19 mav. be formed in the curb l at suitable interva s. Y ff .y

I would haveA it Iunderstood that I desire not to beflimitedto'the precise det-ails of construction herein" shown and described, for various modifications will occur to persons skilled in the art'.

I clairnas my invention:

1. In a concrete building structure, the combination of a curb; an upwardly tapered reinforcedconcrete ridge beam; reinforced concrete rafters sloping downwardly from said ridge'beanr, the up er ends of each of said rafters bein beve ed to abut against and bev supported by the tapered sides of said ridge beam, said u per ends of the rafters Vha ving openings t ierein; a series of bars embedded in said ridge beam, the ends of said bars extending upwardly and out;V

of the curb at the edges of said notches for longitudinal movement, said curb having a further preventing downward sliding movement of said rafters.

2. In a concrete building structure, the combination of a curb; an upwardly ta pered reinforced Concrete ridge beam; reinforced concrete rafters sloping downwardly from said ridge beam,the upper ends of said rafters being beveled to abut against and supported by the tapered Asides vof said ridge beam, Said upper ends of said rafters having openings therein; a series of barsA embedded in said ridge beam and extending upwardly and outwardly from the sides thereof and entering said openings in the rafters-1 for supporting said rafters against series of notches therein in which the lower portlons of said rafters 11e; shoulders on the,

'bottom and two sides of said rafters abut- 20 ting against the inner side of said curb at the edges of said notches for further preventing downward sliding movement of said rafters; and bolts embedded in said curb and projecting upwardly into said rafters, 25

said bolts and said shoulders being substantially parallel to facilitate mounting of the rafters on said curb and said ridge beam. OTTO KITZELMAN. Witnesses:
